The school tours they give are very informative. I would suggest 4th grade and up based on the content. They answer any and all questions that the students (or parents) have. The visit to the 'vault' isn't much to look forward to. You basically ride an elevator down to the vault level and they explain that you can't go into the vault because of security. Understandable. What country wants kids and parents walking around next to their gold?
